You can also Xyz Summon this card by using 1 "Number 33: Chronomaly Machu Mech" you control as the Xyz Material. (Xyz Materials attached to that monster also become Xyz Materials of this card.) Once per turn: You can detach 1 Xyz Material from this card to target 1 face-up monster your opponent controls; Reduce that monster's ATK to 0 and inflict half of that amount to your Opponent's Life Points as damage, then increase this card's ATK by that Monster's ATK before this effect until the End Phase of this turn. Your Life Points must equal 1000 or less to activate and to resolve this effect.
